A Brief Comparison Table

My Experience With Roomba i3 Vs i7

Back in January 2025, I was tired of lugging my heavy vacuum around my 1,200-square-foot home, especially with my dog and cat shedding like crazy. On January 10, I grabbed the Roomba i3+ for $350, lured by the self-emptying perk, and it arrived by January 15.

 The 10x suction (compared to the 600 series) tackled my hardwood floors and low-pile rugs well during a test run on January 20, with the Smart Mapping (post-EVO update) guiding it in neat rows. By February 10, after 15 cleans, it handled pet hair decently, though it missed a few corners in my kitchen. The self-emptying bin saved me time, lasting about 20 days with my mess.

Curious about the upgrade, I snagged the Roomba i7+ on March 5 for $550, drawn by the advanced navigation, and it showed up by March 10. The vSLAM tech mapped my home in one run on March 15, letting me set no-go zones around my cat’s food bowl—something the i3 couldn’t do.

 By April 10, after 12 uses, it picked up more pet hair on my rugs, though the 75-minute battery still needed a recharge mid-clean on my larger days. On June 1, with 30 runs each, the i3+ kept my floors tidy for less cash, while the i7+ shined with multi-floor mapping during a party prep. By June 28, after 50 uses, the i7+ felt sturdier, but both held up against my pets’ chaos.

Living with a shedding dog, a curious cat, and a busy schedule, I’ve pushed these bots hard. The i3+ survived a hairball jam on May 1, while the i7+ dodged my kid’s toys on June 10 thanks to its sensors.

 I run them 5-7 times weekly, loving the i3+’s budget-friendly ease and the i7+’s smart features. The i3+’s single map worked for my one-level home, but the i7+’s 10-map storage would’ve helped if I had stairs. Both outdid my manual vacuum, but your pick depends on space and smarts—let’s explore!
